DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a bracket having a large load-bearing capacity, which can cope with a heavy weight, to a column.

[0002]

2. Description of the Related Art Conventionally, brackets and supporting columns constituting shelves for displaying merchandise in a store or the like are, as shown in FIG.
Bracket 11 has locking notch 12 with locking notch 12 on one side
13 are provided at appropriate intervals, and the support column 21 is provided with an appropriate number of slots 22 for loosely inserting the locking claws 13 of the bracket 11, and the locking claws 13 of the bracket 11 are inserted into the slots 22, Many of them are lowered as they are so that the locking notch 12 is locked to the lower edge of the slot 22.

[0003] However, in this case, when the shelf is formed on the bracket 11 with the shelf board supported thereon, and the shelf is formed, and the product is placed thereon,
The load concentrates on the portion of the locking claw 13 that is in contact with the locking notch 12, and if the load is excessive, the product may be bent or cut off from that portion, causing the product to fall, or vibrating due to an earthquake or the like. The bracket 11 moves up and down and the locking claw 13
There were problems such as dropping off from 22 and dropping the whole product.

Therefore, as shown in FIG. 6 and FIG. 7, two columns 31 are provided so as to hold the columns 31 in the C-shaped members 33 arranged in rows in the center in the longitudinal direction at appropriate intervals. The groove forming member 34 is fixed and configured, and the locking claw 13 of the bracket 11 is inserted into the formed groove 35, and the locking claw 13 is locked in the slot 32 in the same manner as described above. Some of them have been put to practical use. According to this method, the bracket 11 can be more stably mounted on the support 31 as compared with the one shown in FIG. 5, but when supporting a heavy one, there is the same danger as above. In addition, there is a problem that the support itself must be expensive.

The strength of the conventional locking claw against the loaded load of the bracket is determined by the area and thickness of the base of the locking claw and the height of the base of the bracket (vertical width of the base). Points are inevitable.

[0006]

DISCLOSURE OF THE INVENTION The present invention is free from the above-mentioned problems and has a high load-bearing property.
An object of the present invention is to provide a mounting structure of a bracket to a support column, which can be easily attached to and detached from the support column and does not easily fall off.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and has a structure in which a plurality of tongue-shaped tongues are provided on one side of a bracket in a structure for mounting the bracket to a column. On the other hand, the locking claws are provided obliquely downward, and the support pillar is provided with a fitting groove in which each of the locking claws abuts from above and below, and is inclined at the same inclination angle as the locking claws. The locking claw is detachably fitted and locked in the fitting groove of the column by one operation.

That is, according to the present invention, a locking claw provided on one side of a bracket is not formed with a notch for locking, but is formed in the shape of a thin plate-shaped downward tongue, and a support is provided between two plate members. If the locking member that fits and locks the entire locking claw is fixed and the locking claw is locked to the locking member, the load applied to the bracket is received by the entire locking claw and the load is distributed to the strut without difficulty By being able to withstand a large load,
Since it does not accidentally come off from the column due to vibration and the like, and the structure of the locking claw is simplified, the manufacturing cost can be reduced.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view in which a part of an example of a bracket used in the present invention is attached to an example of a column, and FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 3 is a bracket used in the present invention. FIG. 4 is a plan sectional view of an attached state, FIGS. 5, 6 and 7 show prior art examples, and FIGS. 5 and 6 show one state in which a bracket is attached to a support. FIG. 7 is a sectional view taken along line BB of FIG. 6.

1 and 2, reference numeral 1 denotes a bracket, 2
3 is provided on one side with three locking claws provided obliquely downward, and 3 is provided between two plate members 4 and 4 with fitting grooves 5 for fitting and locking the locking claws 2 on the left and right sides. The support pillar is fixed with the provided locking member 6 interposed therebetween, and thus constitutes an example of the mounting structure of the present invention. Although the locking claws 2 are formed integrally with the bracket 1 with the same thickness, it is optional whether the thickness is the same.

According to the present invention constructed as described above, the entirety of each locking claw 2 of the bracket 1 is entirely fitted in the fitting groove 5 of the locking member 6 interposed between the plate members 4 and 4 of the column 3. The bracket 1 is attached to the column 3 by fitting and locking. As a result, the entire locking claw 2 of the bracket 1 is fitted and locked in the fitting groove 5 of the locking member 6. , Bracket 1
In this case, since each locking claw 2 receives the entire load and disperses the load to the columns 3, the load resistance is remarkably improved as compared with the conventional product, and even if vibrations or the like occur, the locking claw is locked. There is no possibility that the claw 2 will fall out of the fitting groove 5.

Further, as shown in FIG. 1 and FIG.
By fixing a locking member for fitting and locking the locking claw 2 of the bracket 1 between the plate members 4 by means such as welding, it can be manufactured very easily, and furthermore, the whole becomes a thin plate. Thus, the appearance is good, and therefore, there is an advantage that it can be used after being attached to a side surface of a column such as a conventional display shelf by welding or the like.

In the embodiment shown in FIGS. 1 and 2, the bracket 1 is formed by a single plate-like member. In the present invention, the bracket 1 is formed in a channel material shape as shown in FIG. Two rows or more locking claws 2 can be formed at the end.

The support column 3 for the bracket 1 in which the locking claws 2 are formed in a plurality of rows of two or three rows has a fitting groove 5 for fitting the plurality of rows of the locking claws 2 as shown in FIG. Locking claw 2
Are formed so as to have the same number as the number of rows. In FIG. 4, reference numeral 41 denotes a spacer member for forming two rows of fitting grooves 5 and 5.

When the mounting structure of the bracket 1 to the column 3 is formed in this way, the lateral deflection of the bracket 1 can be positively prevented, and the strength to withstand a large load can be easily realized.

In any of the embodiments, the bracket 1 can be easily mounted because the tip of the locking claw 2 is guided by the fitting groove 5 only by being inserted in the direction of the fitting groove of the column 3. . In addition, the detachment can be performed by a one-touch operation in a manner similar to the mounting.

In the embodiment shown in FIGS. 1 and 4, the fitting grooves 5 are provided on both left and right sides (front and rear surfaces of the column 3) of the locking member 6, but the present invention is not limited to this. It may be provided on any one side. The plane cross-sectional shape of the plate member 4 is not limited to the illustrated example. For example, the entire surface of the locking claw 2 may be an inner surface of the plate member 4 in the fitting groove 5 such as a substantially convex or substantially T-shaped cross section. What is necessary is just to be able to fit and hold on the whole surface of the.

[0018]

The present invention is as described above. Therefore, when a shelf is formed by mounting a shelf plate on a bracket, even if a heavy article or the like is placed on the shelf, it can well withstand the load. It is possible, and the locking claw does not need to be provided with the notch for locking unlike the conventional product, so the cost of the mold used when molding the bracket can be reduced, and it is possible to achieve the economic effect as well. Become. Further, according to the mounting structure of the present invention, a plurality of tongue-shaped locking claws are provided on one side of the bracket so as to be inclined obliquely downward, and each of the locking claws is brought into contact with the column from above and below. Since the fitting groove is provided so as to be sandwiched and inclined at the same angle as the inclination angle of the locking claw, the locking claw can be removably fitted and locked to the fitting groove of the column by one operation. ,
The work efficiency of attaching and detaching the bracket can be improved.
